摘要: Forecasting the end of the service life of a relay more accurately due to the effects of the load conditions and the environmental conditions can occur through diagnosing the end of service life of the relay based on the time, until the point in time that the actual opening or closing of the relay is detected, from the point in time of the application of the power to the relay or the point in time of the end of application of power to the relay coil by the controlling portion. Forecasting the end of the service life of the relay based on time, increases accuracy because time is a value that is not affected by the external environment. Additionally, because the end of the service life is forecasted based on the actual opening/closing of the relay, not only is it possible to detect immediately a fault in the relay, but it is also possible to eliminate the effects due to individual differences.

摘要: A system for transmission of signals between modules wherein, for example, it is possible to transmit reliably, between modules, information relating to, for example, the actuation of safety devices. A transmission module for transmitting a pulse signal of a specific period, which indicates the existence of information, generates, in time division, pulse signals by a plurality of signal generating units that are provided in parallel, and then combines these pulse signals into a single time series pulse signal. Then an attempt is made to output this pulse signal towards a receiving-side module through a relay for controlling the output, and the signals appearing at a normally-open terminal and at a normally-closed terminal of the relay are monitored to determine whether or not there is a failure, where the generation of the pulse signal is stopped when a failure is detected.

摘要: A relay failure detecting device able to detect reliably a fault in a relay circuit that provides alternating current power to a load through a relay that is a double-pole switch. Individual common terminals of first and second relays are connected individually to a pair of outputs terminals of an alternating current power supply, individual normally-open terminals of the first and second relays are connected to a pair of power supply input terminals, and a dummy load that is driven by the alternating current power supply through a diode between the individual normally-closed terminals of the first and second relays is provided. A fault in the first and second relays is evaluated from the state of operation of the dummy load when the first and second relays are not driven.

摘要: A combustion furnace control apparatus for which an operation control system that ensures the combustion safety of the combustion furnace can be constructed easily. Interlocks pertaining to the safe operation of a combustion furnace are classified as a 1st interlock pertaining to the safe operation of the overall combustion furnace, a 2nd interlock pertaining to the combustion environment of a combustion zone and a 3rd interlock pertaining to the combustion of a burner. Whereby, a common control module judges the state of the 1st interlock and controls the overall operation of the combustion furnace; a combustion zone control module, receiving a control signal from the common control module, operates to judge the state of the 2nd interlock and prepare the combustion environment for the combustion zone; and a burner control module, receiving a control signal from the combustion zone control module, operates to judge the state of the 3rd interlock and control the operation of the burner.
